ratio ring
What’s it for?
The Ratio Ring is a 1x-specific chainring for 12 and 13 speed drivetrains. The chainring features a directional narrow-wide profile to prevent chain drops both while pedalling and when freewheeling over rough terrain. The chainring is currently available for 5 bolt, 110 mm BCD fitment.
ratio ring compatibility:
The Ratio Ring is designed for use with Campagnolo Ekar* 13 speed chains, and with SRAM Flattop* and Eagle* 12 speed chains. The 5 bolt, 110 BCD pattern is the most common ‘road compact’ chainset bolt pattern.
